Abstract

Sulfur dioxide (SO2) is an irritant gas at concentrations above 250 g/m3 which can cause respiratory problems. Sources of SO2 come from burning fuel containing sulfur. Measurement of SO2 levels in the air using the Tetrachloromercurate (TCM)/Pararosanilin method. PT "B" is a processed wood product company with production using sodium metabisulfite as a mixture for making glue for one type of process product. The purpose of this study was to study the interference of sodium metabisulfite in the measurement of SO2 in the air using the Tetrachloromercurate (TCM)/Pararosanilin method. This research is descriptive observational to explain the phenomena found in monitoring the concentration of SO2 based on SNI 7119-7:2017. The SO2 concentration in the 2017 – 2019 RKL-RPL monitoring results at the glue mixing location was 7-191 g/m3. In the second semester of 2020 measurement, the SO2 concentration was measured at the glue mixing location when the product used sodium metabisulfite as an additive. The activation of SO2 is as follows: activation of the mixer after the process is 646 g/m3, filling the glue mixer is 291 - 314 g/m3, the activity without the use of sodium metabisulfite is 11 - 13 g/m3. The results showed that the concentration of SO2 when the product used a mixture of sodium metabisulfite was higher than the concentration of SO2 when the product did not use sodium metabisulfite. Based on the results and analysis, it can be said that there is an interference of metabisulfite compounds in SO2 measurement due to the absorption of sodium metabisulfite by TCM. This research is helpful for contamination parameters in the workplace  and the threshold determination and reducing the accident and occupational illness caused by exposure to chemicals through controlling and controlling potential hazards.

Abstract

Atomic Absortion Spectrophotometer (AAS) or Atomic Absorption Spectrophotometer (AAS) is an instrument for analyzing metals, including: Pb, Cr, Ni, Cd, Fe, Zn, Cu, and Co where the basis of measurement is the measurement of light absorption by an atom. The unabsorbed light is transmitted and converted into a measurable electric beam. The purpose of this study was to determine the performance of the AAS Therma ICE 3000 tool on Cu metal testing using CRM 500 and CRM 697. This is very important because it greatly affects the validity of the measurement results in inorganic chemistry practicum activities, research and testing at the Chemical Laboratory of UPT Lab. Integrated UNS. Performance elements to be investigated include accuracy, precision, detection limit and linearity. From the results of the study, the results obtained accuracy <5% from control, repeatibility %CV count <2/3 CV Horwitz equation, detection limit with MDL 0.065 ppm and R2 for linearity of 0.9999

Abstract

Crafts made from tanned leather can be of various kinds. Wallets, bags or other forms of crafts include using leather as raw materials. Likewise, many watch straps are made with various models and colors, but until now there have not been many watch strap products made from leather scraps. Practical activities at the Physical Testing Laboratory of the Yogyakarta ATK Polytechnic have produced by-products in the form of leather scraps. irregular in shape and size. So far, the Physical Testing Laboratory has not carried out the management process. So that there is a buildup that can result in the accumulation of the amount of residue. The purpose of this study is to utilize the remaining pieces of leather to make higher-value products. The benefits of research add to the contribution of the Education Laboratory Institution by increasing their creativity in managing laboratory waste into a more useful product. This research method is a qualitative descriptive, the equipment used is a sewing machine, cutting mat, cutter, scissors, ruler, silver ink, glue, manila paper and a hole punch. The process of making a watch strap begins with making a pattern, cutting, thinning, gluing, sewing and finally installing the buckle, spring bar and making holes according to the size of the buckle. Produced watch strap products made of leather scraps from the waste of practicum which have high economic value and can reduce waste pollution

Abstract

The existence of a laboratory is very necessary to fulfill curriculum a chievements. Because laboratory is a mandatory facility to hold any practical classes. Undip Vocational School of Marine Construction Engineering Technology Study Program is using the 2020th "Kampus Merdeka"  curriculum, in which one of the practical classes is welding and carried out at the Ship Welding Laboratory using a Multi-Process Welding Machine. The purpose of the welding practicum  provision is to find out the results of welding that carried out by students using data collection method and conducting experimental settings that are adjust ed to the welding data reading. Welding process using SMAW integration of amperage and voltage with due regard to the WPS procedure. From several samples of welding results, it can be seen that some parts may have welding defects.  Welding with the SMAW method using an E6013 electrode with a diameter of 2.6 mm, and with a plate thickness of 10 mm at 50 - 70 amperes, whilst for a 5 mm plateat 48 - 65 amperes, but also depends on the welding clock flown and position.

Abstract

The development of technology is currently growing rapidly, especially door lock technology. The door at the informatics engineering laboratory still uses a manual lock system using a key. There are weaknesses in this system, starting from security, namely currently many people can duplicate keys. While in terms of key care, if the key is lost, you must first go to the key duplication area. Therefore, the research team needs to design a door lock system based on Rfid and Arduino in the Computer Laboratory of the Department of Informatics. The purpose of this research is to keep up with the times, which are all automated, to facilitate the process of opening and closing the laboratory door, and to facilitate maintenance. The materials needed to make this system include Pro Micro, RFID sensor, Selenoid door lock, LED, 5V relay module, ID card and acrylic. This research was conducted at the Laboratory of the Informatics Engineering Department of the Banyuwangi State Polytechnic. The method used is the Research and Development (R&D) method, the R&D method is a method for making a product and testing its effectiveness. The stages of the R&D method are potential and problems, system design, tool manufacture and refinement, tool testing. The results of this study are that the research objectives have been fulfilled in facilitating the process of opening and closing laboratory doors and can overcome security problems and key duplication.
